My Bash Profile

Bash is my favourite shell and here is my .bashrc which has grown substantially over the years as I have added (and will continue to add) more and more useful aliases and functions. These are very useful because they save time and also stop you from having to type in long error-prone commands.

My personal favourite alias is ll='ls -ltr' and I don't understand why some people still type in the long form for such a common command.
